gtk:accel-map-add-entry (path key mods)

path -- a string with the valid accelerator path
key -- an unsigned integer with the accelerator key
mods -- a gdk:modifier-type value with the accelerator modifiers

Registers a new accelerator with the global accelerator map. This function should only be called once per path with the canonical key and mods for this path. To change the accelerator during runtime programatically, use the gtk:accel-map-change-entry function.
